I didn't claim to know, just said that I suspect DL won't be put out of business by AA launching service that's largely exclusive to theirs. DL's current statement is nothing but dishonest propaganda. If they ultimately leave the market, it will be because their ATL flights are no longer profitable, not because of some preemptive and emotional reaction to a city council decision.

And everyone seems to be ignoring the fact that regional businesses are fronting a big chunk of this guarantee, by the way.
